Jamey-Lyn Horth

Women's Flyweight · REAL v1.0 (registered) #17; v1.1 (shadow) #20

Descriptive profile. The resume rank is what has been earned; these statistics are context, not a prediction. A test on Oct 20, 2026 found that career statistics add nothing reliable to age, layoff and experience as predictors of the next result (experiments/REGISTER.md, EXP-2026-10-20-14).

Weight band 15-18: the 10th to 90th percentile of her position across weight vectors drawn near the 70/30 weights. Rating 1,567, deviation 150: measured from 7 UFC bouts; a one-bout newcomer sits near 290.

Age 36 (born 1990-03-30) · Height 5 ft 7 in (170 cm) · Reach 66 in (168 cm) · Stance Orthodox · 197 days since last bout (2026-04-18) · Last five 3-2 · Streak L1

Why she is ranked here

Rating 1,567 is the division's 18th highest of 37 board fighters; the ledger stands at -3.0 (less 3.0 for other losses outside the top 5; losses count for three years); 0 quality wins in 15 years, 0 over top-10 opponents; no form penalty (3-2 last five). Score -0.00 = +0.08 (rating term, 70% weight) -0.09 (ledger term, 30% weight) -0.00 (form penalty); score order put her at #16; the head-to-head rule (the winner of the most recent meeting within three years moves directly above the loser when ranked at most three places behind, six within a year) placed her #17.

Opp. official rank = the UFC media-panel rank of the opponent on the date (C champion, #1 to #15, unranked; n/a before Feb 2013 or where no official board existed). Model p = the predictive model's pre-fight win chance for her (frozen performance-adjusted Elo; bouts before 2020 were in its tuning sample). Linked opponents have a profile.

Rating after each UFC bout from the frozen predictive model (performance-adjusted Elo, data/processed/elo_history.csv; a debut starts at 1,500). The resume rating's history is not stored, so this is the predictive line, which is a different number from the resume rating in the header.

Trajectory

Recent performances run about 34 points behind the rating: fighters this age typically run 54 points behind their rating, and her own recent results recover 19 of those points.

Each dot is one decided UFC bout at her age then: the performance score minus the rating's expectation, on the score's own scale from -1 to +1 (filled = win, hollow = loss; above zero is better than the rating implied; a finish as a slight favourite is about +0.45). The dashed line is the population curve for all fighters; the solid line is this fighter's own fitted level and trend as of the data date, weighted toward recent bouts. One unit sustained over many bouts corresponds to about 695 rating points; a single bout's residual is noisy.

Held-out evidence (walk-forward 2016 to 2026, EXP-2026-10-21-01): the age curve held in every test year; the individual component is a weak signal (correlation 0.06 with the next bout's residual; among fighters aged 33 or over, the lowest predicted quartile won 38% of next bouts against 53% expected, the highest 48% against 52%) and adds nothing to bout prediction beyond the shadow model. No board uses any of it: the rankings answer who has earned the place, not who wins next (EXP-2026-10-20-09). Method: src/mmalab/decline.py; settings: config/decline.yaml (expectation from the resume rating; one unit of residual is about 695 rating points).
